How to fix Vietnam arrival card errors when the visa start date is the same as your arrival date?

For an arrival-form error, temporarily switch to a different visa category, manually edit the visa issue/start date, and then return to the correct category. This field reset reportedly allowed the application to be submitted.

If you arrive on 24 September, a reported workaround is setting the visa field to one day earlier, 23 September. Select another visa type first, edit the date, then switch back; the revised date may remain in the inactive field.

When the system automatically sets the visa date to the arrival date, one workaround is selecting the visa-exemption certificate option, choosing today’s date, and then returning to the single-entry visa-exemption option. A traveler reported that the date stayed saved after switching back.
